[R] ask for help with this R quesiton

question like this: I have data tag and phi, when tag are the same, then phi are the same. like below, tag have value 1 2 3 4 and phi have value .9 .3 1 0. my question is, how can I get the result like tag=c(1,2,3,4) and corresponding phi=c(.9,.3,1,0) tag phi 2.3 1.9 2.3 31 2
